MANUFAOTURE OF C-ASKS, BARRELS, sec., OF GLASS.

SPECIFICATION forming part of Letters Patent No, 253,543, dated February 14,'1882.

Application tiled October 4, 1881.

' To all whom it may concern:

and plunger for making barrels, casks, andA like-articles of glass. Fig.2isa sectional View of a cask with projections cast thereon, on which the weight of the cask is supported. Figs. 3, 4, and 5 are sectional views of casks as made in the mold shown in Fig. 1, showing modicationsof the protecting devices hereinafter more fully described. Fig. Gis a section al view of a Cask having one end cast solid with the sides and the other end inserted and supported on ledges. Figs. 7 and 8 are sections of a butter-triband pail or bucket.

My invention consists in improvements-in the manufacture of casks, barrels, Ste., made in a sectional mold, in which the body of the mold, as well as the plunger, is provided with a heating-chamber, so that the inside as well as the outside of the cask or barrel is thoroughly annealed. The sections of the cask or barrel are then welded togetherin the ordinary and well-known manner.

It also consists in providing the cask, barrel, 85e., either with wooden hoops held in place by tie-bolts, or with hoops covered with rubber,

. or in covering the entire barrel or any portion thereof With a rubber cover to prevent the cask, barrel, Ste., from becoming injured.

It consists, further, in certain details of construction more fully hereinafter set forth, and

- pointed out in the claims.

In Fig. 1, A designates the mold, and B the plunger, both of which are provided with heating-chambers b, as is more fully set forth in another application (marked hCase A) filed even date herewith, and the object of the heatingchambers is to so heat the molds that the glass will not chill while being placed therein, and to continue the heat after the article is formed,

(No model.)

so as to anneal or harden the same prior to removal from the mold.

In Figs. 2,3, and 5, C indicates finished casks of glass, the Open ends of the sections composing the same having been properly trued and welded together by means of a band of glass.

In Figs. 2 and 3, c indicates the strengthening, protecting, or supporting badscast thereon or otherwise secured thereto, by which means the Cask is protected from injury. In Fig. 3 I have shown the protecting-bands as covered with india-rubber or other analogous material, c. j

In Fig.`4, D represents a cask made of sections of glass, as formed in the mold shown in Fig. 1, properly welded together, and strengthened or protected by wooden or other hoopse c, which are connected and held in place by rods d, the ends of which are screw-threaded to receive the nuts e, by which means the hoops are held in place, and when occasion requires it they can be tightened up. In this Inode of strengthening or protecting the casks or barrels the end hoops are made wider, so as to project over the ends of thecask and proteet the same from breakage by suddenjars.

In Fig. 5 I have shown still another form of protecting the cask or barrel, which consists in coating the cask, including the chine, with india-rubber, as indicated at f. For many purposes the covering of the cask with rubber will be of great value as a protecting medium from blows or jars during'transportation, &c.

Fig. 6 indicates a cask the sides and one end of which are pressed or cast in one piece, the other end being provided with a shoulder or offset, g, to receive and support the head F, which is cemented thereto-or welded therein. The form of cask shown in Fig. 6 is also provided with strengthening-ribs It at the ends and along the sides.

In Fig. 7 I have shown a section of which the casks or barrels are composed utilized as la tub for packing butter and other analogous uses, with a recess or rabbet in the top, which receives and supports a cover of glass or wood. In the samegure I have shown a pail or waterbucket made of glass, the advantages of which, especially forl dairy uses, willbe obvious to any one skilled in this art.

IOO

I am aware that easks or barrels have been heretofore made of glass in sections and welded or otherwise secured together; also, that molds for coiiins, in which the body of the 5 mold was provided with a heating-chamber while the plunger was made solid, are not new, and therefore disclaim such.

I am also aware that lamps have been made in sections and welded together. By annealio ing only the outside of the article and not the inside it is liable to crack.

I am further aware that vessels or recept-acles for containing.liquor7 Svc., have been covered with a thin coating of leather, canvas, or

15 analogous material to give them the appearance of carpet-bags; but such coating would not protect them from injury.

Having thus described my invention, what I- claim, and desire to secure by Letters Patent, 2o IS- 1. The combination of mold having a heating chamber with a plunger also provided with a heating-chamber, for the manufacture of casks, barrels, 85e., and for the purpose of annealing them through the entire structure, 25 substantially as specified.

2. A cask, barrel, or analogous article made of glass and annealed through its entire structure, and provided with strengthening and protecting hoops or surfaces, substantially as 3o specified.

In testimony whereof I hereby atix my signature in presence of two witnesses.
